The Sun Hydraulics DPBMKBN (DPBMKBN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a pre-set threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. This model is interchangeable with direct-acting versions, sharing the same cavities and flow paths. The DPBMKBN features Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or cavity machining variations. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve allows for modulation between two positions and is not bistable, with maximum valve leakage at 110 SUS (24 cSt) limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation requires a torque of 30 to 35 lbf\u00b7ft (41 to 47 Nm), and adjustment involves up to five clockwise turns using an internal hex screw size of ^5/32 inch (4 mm). The locknut requires a torque of 80 to 90 lbf\u00b7in (9 to 10 Nm) with a hex size of ^9/16 inch (15 mm). Weighing approximately .60 lb (.30 kg), this model includes Viton seal options for enhanced durability and compatibility with various applications.

Normally open, pilot-operated, 2-way directional cartridges are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve setting. If this is a problem, the direct acting version of this valve would be a solution.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
